As lthe paper.- is ,fed forwardly, 'a l `sheet at a time by hand (orautomatically by means not shown), along the table 320, itis gripped iby grippers carried by -the platen roller 140 while the type bed'2()4 isat the left `hand end. of the' machine (Fig. 11),.-t`he platen in thisligure rotatingina righthand direcf` tion.V This carries "the .sheetdown around the platen and between itand the bed i which is concurrently.moved toward the. right andv then, after printingV is completed,

the grippers 4carryythe.sheet around the top i i of the roller anddischargeit wherel it' passes to the delivery table350, as the plat-enstarts on; its A.second .st'roke. During this 'second stroke,'theplatenv is raised-out of contact withthegbedand the bed is -returnedidly beneath the platen to the lefthand pol sition, the 'bed beinginkedduring such movement.v Accordingly, the ,printing .is l ef-f fectedlat-,everyalternate rotation of Vthe platen which` corresponds to eachmovement in the. corresponding direction of the y bed, i the paper beingdelivered andthe bed `re-` turned' andre'einkedon the other alternata;`

Each rollfrainexconiprises a series. of 1 rolls 23 yourdr naled betweenlongitudinal bars124, the rolls resting on bed.`l f f vDepending from`the underside of the type bed20 is-'a vertical housing 30 in which is aivertically slidableblock 31, see Figs. 5

and 10.5 This blockis connected by a pivot VpinA lwith. a drivingsprocket chain 32,

mounted on two sprocketiwheels 34' and '85 and having upper and; lowerhorizontal reaches as shown. When 'the vpivot pin 36 of the lblock istraveling on either of the horizontal reaches, the type bed, is moved ata corresponding speed` .in the direction or' travelt As thelinkcarryingthe pin starts traveling around the outer portion of theperiphery of either :wheel 34 or 35, the block '3l slides alongvtheguideway 30 and toward the centerithereoifand the speedl of movement oflthehed diminishes until itis stopped when the ,pin is in a'honizontalplanethrough the;A axes of the wheels -34 and Inf the vnext quadrant offiiioxvemeng thebed starts f in the opposite direction and :graduallyins `creases its speed until-it reaches its full`4 speed when` the pin,comes` to the bottom;

The pivot pin is `journalled in the block,the head 42 is I a channel-shaped member` of; substanv. tiall'y the samelength as a link of the' sprocket chain and'it takes the plane of'alink', carrying-pinsil pivotally' connecting thefadjacent chainlinks 44and 45.

f outer ends.

The sprocket 35 referred to, which is the idler, is preferablyadjustably mounted. To effect this, l mount it loosely on the eccentricend 51 ol a shaft 50 (Fig. 11) which is Y j ournaled in bearings 52extending downwardly from the 'frame bed 2. A suitable.

lever 54 on the shaft' furnishes `means for turning it and the screw455, passing through 'a' slot 2) .in the lever, enables it to be lockedin'adjusted position. By this means,

I may maintain the chain always taut, to

eilect an accurate drive of the type bed.

The sprocket wheel 34 vis tliedriving member for the chain described.Torotatethis' wheel, it is'con-venient to secure it. tightly on theshaft 59 which is secured to the driv ing wheel 60 driven in anyconvenient man# l ner. As sho-wn in Figs. l1, 4 rand v5, l have.connected the wheel 60 by a'sprocket chain,

61 with a sprocket pinion 62'on the shaft- 63 mounted in brackets. 64andy carried by the frame legs. On this shalt (i3 is a belt pulley 65. Abelt'G is shown as running over this to a driving pulley 67 on the motorsuitably mounted between the frame legs;

It will be seen from the construction de#V scribed, .that the driving`mechanism `causes a given direction as indicated by the arrows in Figs.1, 2 and l/Vhen the drivingblock 31 is traveling the lower krea-cli oithis chain,

the type bed is moving toward the Vright hand,

in Fig. 1 yand is effecting-.itsprinting operation. When the block istraveling the upper reach ofthe chain, the type bed is moving toward theleft in Fig. 1, which movement is idle except that the type is beinginked theL sprocket chain to travel continuously in ioo To prevent jaras theftype bed' comes ino v nientarily to rest, .intermediate itsalternateV movement, f1 provide the dash pot construction shown in Fig.5. Extending from the opposite edges oi" the housing BD which dependsfrom the ytype bed are twohorizontal I rods 70 which carry plungers 71onY their Carried by the -llramey bed in alignment with these plungersare dash pot j cylinders 73 eachof which has ears 74v (Fig.Y r4)"byYwhich it is secured to the 'frame bed.

The dash pot cylinder is entirely open at its inner eiidand chamfered atthis end asV` 'shown at 75 to enable't-he rready entrance' of vtheplunger. At the oppositeend of the i cylinder is an opening 76, acrossthe inner 'lace of which extends alilexible valve sheet f Y 77. A petcock 78 leads from' the cylinder in front 'of the valve sheet.

As the type bed is approachingeither end of its movementythecorresponding piston 71 enters the adjacent dash pot cylinder, therebycompressing the air-therein, closing the check valve 77'and forcingthe-air out through the pet cock. Any desired amount of retardation maybe ellected in varying` the amount of closure of thepet cock. Whenvthebed has come to rest, the `return move-r ment is free .from theV dashpot retardation,

as thelcheck valve opens onthis movement and admits air to `thevcylinder behind the piston. The means described is accordingly enabledto insure the inertiaof the bed being properly taken up as'the bed comesto momentary rest, thus preventing jar on the mechanism or undue -wearon'the parts, withwith the'y resumption of" out interfering movement inthe opposite direction.

The inking `mechanism v comprising a fountain and ductor,'distributorand form rolls is best shown in Figs. 3, 7 and 8. The

frame of the inking mechanism consists of two upright plates 81 and 82mounted on theV frame bed, these plates being braced by a crossniember83 which forms part of the ink fountain, and frame'brackets 88 and 89.pivotally connected with these plates byv means of the shaft of thefountain roll 87. This cross member carries spring plates 85 pressed byabutting screws 86. against the fountain roll `87 `journaledginy'theframe plates, the ink lying `inthe trough-shaped space between thespring-plates and fountain roll. 90 indicates a ductor roll lmounted in'movable arms 91 and adapted to carrythe ink from the fountain rollto'atransfer roll 93 mounted inthe bars 88 and 89. 94 indicates acomposition roll receiving 'the ink from the` after described. Thislink,operates an armj 101 carrying a paw1x102v adapted to engage the teethof'a ratchet wheel 103 mounted on the shaft carrying the fountains'roll. The movement of the link issuflicient to` carry the pawl overseveral of the ratchet teeth. I

have shown an adjustable vplate 105 having' a,v flange 106 overhangingthe .teethto limit the and. the mechanism *for operating it withV f Vparticular reference to Figs. 2,16, 7 8 and .115 t number of teeth to beengaged by lthe pawls. This plate has an arcuate slot 107 through whicha set screYs7 108 passes into the frame plate 82. Byloosening'this screwthe plate may be swung` and the flange i106 thus `brought closerto orfarther from the nose of the pawl 102. When the nose strikes the flangeit rides up on-it and the rest ofits travel in idle direction is freefrom the ratchet teeth and on the return stroke it operates only onthe-teeth V,left available after the pawl clears the flange.

The same link-100 mayalso loperatethev ductor roll. As shown the arms 91carrying the ductor roll are rigid on ashaft'110 on which is secured arock arm 111 connected by a linkY 112 with the "link 100.v

The .rollers 280 are fixed axis by :reason of being mountedon a ried in arms-282 and has o n its ends rollers 283 engagil g smoothcylindrical surfaces on the drum, The-arms y282 are mounted'on a movableframe consisting ofv twogbars285 hinged at 286 to the frame membersv147v and 148 and connectedattheir oppositeends by a cross bar 288.yThis construction enables the Vrollers 28()` and otherpartsto behereinafter vdescribed .carried bythis removable frame :to be swungidly, out of the way as indicated inbroken lines in Fig. 6, to lallowaccess to thel upper portion of the platen and thus to its interior. IReverting to the. ejecting VVmechanism, the receiving support 29.0consists of separated plates .spaced laterally out of `registration withthe gripper lingers and carried by the curved sheet metal plate 291mounted on a square bar 292 having trunnions 293 at its ends mounted inthe framemembers 1.47 and 148. Rigidlly mounted, on the bar 292 are apair of pla-tes 295 which provide bearings for the shafts of thedelivery rolls; that is to say, the rolls 296,297 and 298 have shafts300, 301 and-302 respectively, which On the shaft 300 is a pinion 303meshing with an idler V304 which .meshes with a gear 3051 in the form ofa ring secured -to the end of the platen, as shownin `Fig. 9. The idler304 a stud carried by anarm 307 is imounted on rigidly mounted `on thesquare bar y292. The

pinion 303 on the shaft 300- also meshes with fan idler `308 whichmeshes with a pinion 309ontheshaft 302. The .squaregbar carriesalsoadeilector plate 310 extending transverselybetween the rollers296and298.

rlhe forward yedge 329 ofthe paper table lies just in front ofthe crossbar 288 of the movable upper frame heretofore referred'to,

and the pile of paper lies on the plate 32() Y i and-also on the .crossbar 288.. Secured to the paper table is a side kguide plate 330 which isshown as adjustably held in place by bolts .331 extending through theside guide and occupying transverse slots 332 shown in broken lines' inFig. 3 inthe paper table, the bolts having headsbelow the slots.-

The ,late 335 serves to deflect the manually fed' sheet upwardly so thatit will al ways strike the stop fingers 340,'and it is immaterialat whatstage of the rotation the sheet reaches this position, provided itliS-in this position whenthe gripping lingers wardly.

The tympan sheet for the platen `designated 360 is anchored at one endby an eccentrically mount-ed rod 361 which extends across the platen andis adaptedl to clamp the sheet against theinwardlyy thickened portion362 of the drum shell. `This shaft has a squared end by which'a socketwrench may turn it to bind the tympan sheet, a ratchet lwheel 363 andpawl 364, Fig. 6, servingto hold it in locked position. The other end ofthe tympan sheet passes through a slot in the squared shaft`365journaled in the platen and likewise having a squared projecting end fora socket wrench and having a ratchet wheel 366 with which a pawl 367coacts. The squared end of either shaft is 'rendered accessible for 1the application.` of asocket wrench bythe openings 369 in the frameplate147 supportingthe` platen.V The tympan sheet is-kept `clean-by a brushV37() (Fig. 7) carried by a woodenbar'371 70 f mounted on a steel strip372 secured at its*r ends to the framefmembers 147 and-148.
